Even if it were possible, it's certainly not going to be like in the movies where you're in a mirror universe and 99% is the same. The world as it exist is the result of so many random events, throw things off even a little and somebody will wipe right instead of left on Tinder and meet someone else and everything diverges from there. If you go back with the intent to "fix" the past it's not going to happen, you're basically erasing your timeline and replacing it with something new.
